PERFORATOR.

SPECIFICATION forming part of Letters Patent No. 622,088, dated March 28, 1899.

Application'filed J ahuary 9, 1 897.

To wZZ whom it may concern:

Be it known that I, EDWIN R. STORM, acitizen of the United States, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Perforators, of which the'following is a specification.

This invention relates to perforating-machines.

The main object of the invention is to provide an improved machine for punching holes in ribbons of paper or other suitable material,

- such as are used for making and breaking a telegraph-circuit in certain forms of automatic telegraphs, the holes being suitably arranged relatively to each other in the ribbon, so that when it is drawn through a suitable telegraph transmitting apparatus in circuit. with a distant receiver the desired message will be sent. Each message will be composed of letters, characters, syllables, or words, each of which is represented on the ribbon by a distinguishable combination of holes.

In this machine the punches are not moved directly by the operator, but by mechanism operated by a motor and brought into cooperation with the punches when the operator moves a finger-key. There are as many keys as distinct characters-that is, one key for each distinctcombination of perforations representing aletter, syllable, or word to be made. Each key controls the number and arrangement of punches which will be moved forward at a time, and consequently the number and arrangement of holes punched in the ribbon. Each characterthat is, the holes representing itis completely punched automatically on the operation of .the corresponding key, and after the holes are punched the ribbon is automatically moved forward a distance equal to the space occupied on the ribbon by that character plus the space between two consecutive characters.

By means of the spacing device employed in my improved machine it becomes possible to save the time required to strike a keyfor the spaces between words, since the mechanism controlling the spacing is so arranged that by depressing the space-key coincident with any character-key the space is prolonged to the proper distance between Words.

In this machine there are preferably three Serial No. 618,579. (No model.)

rows of punches, the central row being de signed to form a central row of holes at regular distances apart in the ribbon being perfo rated and with which pins in the periphery of a feed-wheel in the telegraph-transmitter with which the ribbon is to be used engage to draw the ribbon along. The two outer rows of punches are designed to form character inafter described and particularly pointed out in the claims.

A represents a base, to which are secured frame-pieces A A parallel-bar frame A cushion-pieces A A, socket-bars A A, and cushion-piece A Figs. 1. and 2. To uprights A A is secured a top plate or frame 15, Figs. 1, 2, and 3, provided with boxes 1 1, fitted with segments 2, Fig. 16, wear being taken up by screws 2 2". The boxes form bearings for shaft 3, having a clutch 4 with a bifurcated trip, hereinafter described, wheels 5 6, and

cams 7 8 9. Screw 2 is placed back of the bearing, Figs. 15 and 16, to prevent loss of motion due to wear of the bearing.

5 is a fly-wheel, and 6 a pulley or gear-wheel secured thereto, to which power is applied from any suitable motor. Vheel 5 is loose on shaft 3, but held in position between clutch 1 and nut 5', which is locked by set-screw 5", Fig. 1-1:.

Cam 7, formed with a projection 7 on one side, Fig. l, operating on wheel 10, loosely revolving on shaft 11, fixed in the sliding head 12, moves the head forward. The two cams 8 act upon straps 13, formed on the links 14., which are connected by the joint 15 to lifting-bar 16, which slides vertically in ways 17, and raise and lower said lifting-bar and with it the cushioned arm 16, attached thereto, 16 being the cushion, which is on the side of arm 16 toward the parallel bars. In Patent No. 575,197 I have shown cams 8 of such irregular shape that they operate to first raise, second, hold stationary, third, lower, and, fourth, hold stationary the lifting-bar, each movement occupying practically onequarter of a revolution, but have found in practice that this construction does not operate perfectly when the machine is run at a very high speed. 1 have in the improved machine herein shown employed eccentrics or cams 8 having regular curved peripheries, preferably true circles. \Vhile these theoreticall y are always moving the lifting-bar up or down, there will be a time between the main up-and-down movements when the lifting-bar will be practically at rest, and this time is suflicient to allow the punch-operating device 12 to operate the selected punches before the blocks are withdrawn from behind them. Owing to the improved construction the machine can be run more rapidly and runs more smoothly than the machine of said patent. Rapid and smooth operation is further increased by use of the spring 19 and a cam 7 ,that only positively operates the device 12 in one direction. Cam 9 operates the paper or ribbon moving device.

Sliding head 12, Working on ways 18, fixed to plate 13, is provided with retractile spring 19, a drawback-plate 20, socket 2l,and grooves 22. The retractile spring, fastened at one end by screw 23 to sliding head 12 and at the other end by post 24. to top plate B, tends to draw head 12 back, holding wheel 10 against cam 7. The drawback plate or fork 20 has projections 25, adapted to work againstcollars 26 on punches 27 28 in such manner as to draw the punches backward with head 12. Both outer punches 27 and middle punches 28 work in holes 2.) in punch-head 30. Holes 29 are enlarged at their outer ends 31, so that punehings will readily escape. The punchhead 30 is secured to top plate I provided with rabbet 32, Fig. 4, to insure the proper placing of the punch-head and to resist the shock or thrust of the punches. Punch-head 30 is provided with a ribbon-receiving slot or way 30.

Socket 21, Figs. 2,3, 4, and 5, receives and guides block 33, adapted to slide through the socket and along rabbet 34, which is in aplane between the planes occupied by the upper ends of blocks 35. Block 33 serves to fill the space between head 12 and the inner ends of the central row of punches. Punches 28 in my improved machine are provided with a spring 28', Figs. 4 and t, to move the punches forward with the drawback plate 20, that block 33 may be free to enter behind punches. The spirals 28" of the springs occupy notches 2S in the punch-supporting block and the ends of the spring rest in grooves 28, being held in place by a top plate. Grooves 22, formed in the sliding head to receive blocks 35, are spaced to bring blocks in line with the punches, one block back of each punch, and to permit blocks 35 to rise and fall freely in a vertical line.

Blocks 35, operated by rods 36, links 37, and parallel bars 38, are adapted to slide in grooves 22 and have a longitudinal channel 39, connecting with a transverse hole to receive the formed end of rods 36, Fig. 4-. These blocks are shown in two parallel series on different le'vels, one series being in position to cooperate with the lower row of punches and the other series in position to cooperate with the upper row, and when raised serve to fill the space between head 12 and the ends of punches 27. These blocks may be circular in section instead of rectangular, (see 35, Fig. 6,) in which case instead of grooves 22 there would be circular holes 35.

Rods 36, provided with eyes 41, fitted to channels 42, formed in links 37, are held to place by screws 43. (See Fig. 9.) Links 37 are attached by rods 44 to frame-piece A and are jointed to parallel bars 38, which are jointed at the other end to links 45, which are provided with channels'42, in which are fitted the eyes 41 of rods 46, secured to place by screws 43. Links 45 are fastened by rods 47 to frame-piece A Fig. 1. This construction causes bars 38 when moved to continue parallel to their original positions, so that rods 36 46 will be moved the same distance whichever assembling-bar 48, placed underneath and working against bars 38, is operated. Parallel bars 38, links 37 45, rods 36 46, and blocks 35 are in this machine nearly balanced by springs 49, having one end fixed to link 37 and the other end to adjusting-screws 50 in top plate B, Figs. 1 and 2. The parallel bars 38 rest on cushions A A The assembling-bars 48, pivoted by pins 51 to blocks 52, resting on cushions A furnished with the projections 53, are operated by the lifting-bar 16 through catch-bars 54. The blocks 52, bored for pins 51, have an edge channeled to receive theends of the assembling-bars 48 and are halved on and fastened to the recessed bar A which is secured to base A, Fig. 2. Cushion is formed of felt, rubber, or other material let in channeled bar A secured to frame A. Projections 53 on assembling-bars 48 are so arranged on each bar as to come in contact with the particular bars 38, controlling punches 27, required to form the character desired. There are as many bars 48 as characters for which the machine is arranged. The catch-bars 54 terminate in handles 56, have projections 57 58, holes 59 60, and are jointed to the assembling-bars in such manner as to allow them to move on center 61, Figs. 2 and 7. Preferably each catchbar 54, of which there is one for each assembling-bar, is formed with a circular depression 62, into which the rounded end of its assembling-bar 48 fits and in which it is held by screw 63, Figs. 7-' and 7 The projections 57 are made to fit over and engage lifting-bar 16 when catch-bars 54 are moved forward in position. (Shown in dotted lines in Fig. -2.) Projections 58 come in contact with the oscillating frame 64 on a rock-shaft and oscillate it when the catch-bars are moved forward to engage bar 16. Holes 59 are furnished with swivels 59', to which are fastened retractile springs 65, one for each catch-bar 54. The other ends of springs 65 are held by screws 66, with set-screws 67, .to tension-bar 68, which works in ways 69 and has regulatin g-screws 7 0, Fig. 2. Holes 60,which receive rods 71,communicate with semicircular recesses or channels on the rear sides of catch-bars 54 to receive the eyes on the ends of rods 71, as shown by dotted lines in Fig. 2. The rods are threaded at one end and screwed into pieces 72. Pieces 7 2 are jointed at 73 with fin ger-keys 74, having tips 79, and move on fulcrums 75 in block 76,

channeled to receive the keys. Block 76 is fastened by V projection 77, fitting into a corresponding groove in bar A, fastened to base A,and by screws 78. The several banks of keys are so pivoted on fulcrums 75 as to equalize the leverage as nearly as possible and consequently the force or touch required on each key to draw its catch-bar 54 forward and overcome the resistance of spring 65.

Rock-shaf t frame 64,workin g on pivot-points 80, normally held against projections 58 by spring 81, is provided with an arm 82, attached to rod 83, jointed at 84 to stem 85 of trip-piece 86, Figs. 1, 2, 14, and 15, forming one member of the bifurcated trip of clutch 4. In this machine the stem works loosely in fixed block 87 to allowthe trip-piece to have a backwardand-forward as well as an upward-and-downward motion. Trip-piece 86 being normally held backward against wedge-shaped end 88 of fixed block 87 by spring 89, Fig. 15, is made to engage bolt 90, which is adapted to slide in clutch 4, and is provided with a transverse groove 91, into which fits trip-piece 86 to draw the sliding bolt backward or release it, as required. Spring 92 tends to press the bolt forward into holes 93, sunk in balance-wheel 5, locking wheel 5 by clutch 4 to shaft 3. The other member of the bifurcated trip, which is extension 88 of fixed body 87, is wedge-shaped and fits against enlarged end 4 of clutch 4 in such manner that as the clutch revolves, carrying with it bolt 90, it enters groove 91 in the boltand partially withdraws it, compressing spring 92, the wedge-shaped extension being purposely formed a little too narrow to completely withdraw the bolt from holes 93. Completion of the withdrawal of said bolt is effected by part 86 entering groove 91 as piece 88 leaves it, (see Fig. 15,) which has one face beveled to match and complete the wedge shape of 88 and is made a little thicker than necessary to engage the bolt from the balancewheel. A shoulder 4 on the enlarged end 4 limits the upward movement of trip-piece 86 and prevents said trip-piece from striking or catching on the bottom of groove 91. By making this extension a fixed member of the bifurcated trip the thrust of the shaft, acting through the bolt, is taken by said extension and the frame supporting it until the thrust is no longer in the direction of movement of the movable part of the bifurcated trip, but is across such direction, acting against the frame, but not against the spring 81, which holds the movable member of the trip against the bolt. Hence a light spring will serve to hold said movable part in place and a light touch on the keys will withdraw it. Spring 89 is compressed by the resistance which spring 92 offers to the withdrawal of the bolt from hole 93, which is effected near the close of each revolution of shaft 3. Bolt is formed longer than clutch 4 that end 94 may engage with spring 95 when the bolt is withdrawn from holes 93. Spring 95, held at one end by post 96 and regulated by screws 97 and 98, acts against end 91 of bolt after it has been withdrawn from the drive-wheel and overcomes the inertia of shaft 3 and tends to return it to proper position should inertia have carried it too far, while spring 89, compressed by the resistance to a complete withdrawal of bolt 90, moves trip-piece 86 with the shaft when returned by spring 95. \Vere piece 86 movable only vertically, the bolt sliding along its inclined surface and disengaged thereby from the wheel would, upon the return of shaft 3, by spring 95 slide back against the wheel and partially engage with holes 93, producing a clicking'noise as the wheel continues to rotate, and would soon wear the holes and the end of the bolt, making engagement uncertain. Giving piece 86 the backward and-forward motion and using spring 89 overcomes said evils and makes the piece 86 automatically adjust itself to any change in the bolt or in its position. Screw 97 increases the tension of spring 05. Screw 98 regulates the position to which the shaft is returned.

Rods 16, Figs. 1 and 12, attached to links 45, are formed so their upper ends work freely in holes 09 in block 100, secured to top plate 13. Block 100 is formed with bearings 101 102, Figs. 11 and 13, which receive slidingrod 103, formed with a head 101, fitted to work in slot 105, moved forward by lever 106, fulcrumed at 107, and actuated by one of the two space-keylevers 71, Figs. 1, 11, and 13, jointed by the single finger-tip 108. Rod 103 and lever 106 are returned to position by spring 109. On sliding rod 103 are blocks 11.0, freely moving in planes perpendicular to the rod and held in position by pins 111 112, so as to move forward and then backward in a body. Ends 113 of blocks rest in rabbet 111 in block 100, resting over or upon the ends of rods 16 and actuated by them, but when resting on rabbet 111 are free to move under ends 115 of blocks 116, fulcrumed on rod 117 and provided with retractile springs 118, at tached to rod 119. Rods 117 and 119 are fixed to top plate 13. Blocks 116 are provided with pins 120, which are staggered and set to work against the adjoining left-hand block in such manner that all the blocks to the left are raised with the last block, as in Fig. 13. Each block has one pin 120, which projects on the left side only to a distance nearly equal to the thickness of the adjoining block. The blocks are of uniform length; but the reduced ends 115 are made alternately long and short, as shown at 115 and 115, and the short ends have notches 115. From each bar with a long end a pin 120 extends into the notch of the next bar and from each bar with a short end a pin extends under the long end of the next bar, as clearly shown in Fig. 25, which is an inverted view of several ends 115 with their pins. Ends 121 of blocks 116 are cut to form shown,- forming in series a sectional ratchet or rack, into which works pawl 122 in arm 123, jointed by pin 12-1 to lever 125.

Pawl 1.22 is held to place by spring 126 and arm 123 works over ends 121, being held to place by top guide 127 and side guides 128 129. (See Figs. 3 and 12.) Lever 125, fulcrumed at 130, is moved toward head 30 by spring 131. and is returned to position by cam 9, working against the end One end of spring 131 is secured to top plate B by screw 132 and the other end to lever 125 through hole Lever 125 is provided with and reciprocates rods 134 135, rod 131 being a connecting-rod between lever 125 and block 33. Red 135, jointed to lever 125 by pin 136, has one end furnished with a rack or series of teeth 137, working in pinion 138, fixed to feedwheel 139, preferably provided with pins 110, adapted to fit in the feed-holes punched in the paper strip, feed-wheel 139, working on shaft 111, fixed in top plate 13. Rack 137 is held against pinion 138 to mesh with it by the arm 112, Figs. 3 and 18, duringmovement in one direction of each reciprocation, arm 142, having the indent 14:3, fulcrumed by screw 11-1 to top plate B. The indent 143 is formed to receive end 145 of lever 1 16, fulcrumed at 147 to top plate B. Lever146, bent to pass underneath rack 137, is provided with teeth 118, spring 119, and end 150, formed to work on cam 151 on one end of cam 8. Teeth 14.8 engage pinion 138 and lock it. Spring 1419 tends to disengage teeth 14:8 and pinion 138 to move end 115 out of indent 113, (see Fig. 3,) forcing arm 142 toward pinion 138, compelling rack 137 to mesh with and operate it. End 1.50 works against cam 151, shaped to force teeth 14:8 in engagement with pinion 138 and formed end 115 in indent, freeing rack 137 from pinion 138 during part of the revolution of shaft and allowing the retractile spring 149 to act during remainder of the revolution. Piece 152, fastened to top plate B, is formed to hold the paper strip on feed-wheel 139. Where a center line of feed-holes is not used,the lever 153, fulcrumed at 155 to top plate ll, with roller 151, Figs. 19 and 19, pressing against feed-wheel 139, may be used. Lever 153 is provided with retractile spring 156. Piece 157, fastened to top plate B, is formed to lift the strip from feed-wheel 139 and direct it out from the machine.

The working parts described, except keys 79, drive-wheels 5 6, slot 30, feed-wheel 139, and pieces 152 157, are protected by a cover 0, formed so that a portion 0 will guard the finger-keys and a portion 0 will serve to hold copy.

The strip or ribbon moved forward by feedwheel 139 from a suitable reel 158 passes over arm 159,through tension device 160,un der arm 161, in slot 30, and over feed-wheel 139, under the piece 152 and in front of the piece 157 and out from the machine. Reel 158, fastened to top plate B by arm 162, has a loose spool 163 freely working on fixed shaft 161-, Figs. 1 and 3. Spool 163 has two spurs 165 to engage with the wooden core of a paperroll and a ratchet-wheel166 on its lower edge,

operated by pawl 167, jointed to arm 168, fulcrumed at 169 to top plate Band operated by retractile spring 170 and link 171. The pawl 167 is controlled by arm 159, ful'crumed at 173 to arm 162. Arm 159 and pawl 167 are connected by spiral spring 174. Retractile spring 170 is jointed to arm 168 at 175 at one end, the other being secured by a screw 176 to top plate B. Link 171, jointed to arm 168 by screw 177, rests againsthead 12 and is moved forward by it, retractile spring 170 returning it to position. Vhen manifolding of the strip is required, additional reels may be used, operated through the arm 168 by additional pawls 167 or by rolls superimposed on the loose piece 163 and fixed shaft 164.

Tension device 160 is composed of a fixed plate 178, Fig. 8, movable plate 179, adjusting-screw 180, compression-spring 181, spur 182, guide-pin 183, and cover-plate 184. The fixed plate contains a hole for reception of the guide-pin and is rabbeted on top to form a check or stop for cover 184. The bottom of the rabbet is bored and tapped to receive a screw 185 to adjust the cover 184 to the width of the paper strip. The movable plate 179 is .fitte'd to work on bottom piece 186, is bored to receive the end of guide-pin 183 and point of spur 182, which holds the movable plate against the fixed plate through the action ofcompression-spring 181, which may be made to fit inside, as in Fig. 8, or over the spur, as in Fig. 8 The force of compression-spring 181 is regulated by screw 180 working in arm 187. Arm 187 supports the pivot of top piece 184. The fixed plate 178 is attached to arm 188, fulcrumed at 189 and regulated by spring 190 and tension-screw 191, or is attached to body 192, Figs. 17 and 3, sliding in groove 193 in top plate 13, made parallel with slot 30. Body 192 is held in groove 193 by screw 194 in slot 194, Fig. 3, and washer 195 and is acted upon by retractile spring 196, having one end attached to washer 195 and the other end attached to arm 197. Arm 1 6l,fulcrumed on pin 198, controlled by screw 199 and com- )ression-s )rin 200, Fig. 20 revents the a-' per strip from jumping up in slot 30 and losing its alinement.

Fig. 3 is a plan view showing a tension device, such as shown in Fig. 17, suitably mounted on plate 13, the pawl-lever 168 being so shaped and arranged as not to interfere with thenecessary movement of the tension device.

Figs. 21 and 22 show, respectively, groupings of punch-holes in head 12 and of punches for preparing perforated strips with and without a central row of feed-holes.

The operation of the described mechanism is as follows: An operator desiring to produce in a ribbon or in ribbons perforations corresponding to any particular character or combination of characters presses down the key on which it appears, turning it on its fulcrum 75, which causes rod 71 and the corresponding catch-bar 54 to move, carrying projection 57 over lifting-bar 16 to the dotted position in Fig. 2. The same movement carries projection 58 on the same bar against the rock-shaft arm or frame 64, turning it on its axis and carrying with it arm 82, pulling down rod 83 and,

trip-piece 86, which permits bolt 90, pressed out by spring 92, to move into engagement with the drive-wheel 5, looking it by means of clutch 4 to shaft 3. This is all that the touch of the operator on the key has to do namely, to move one bar 54 to engage bar 16 and to pull down the movable member of the trip to release bolt 90, connecting the drive- Wheel to the shaft. All other movements are produced automatically by the mechanism and driving-motor. Shaft 3, being thus put in motion, turns cams 7 8 9. The two cams 8, acting through straps 13 and links 14, cause the lifting or moving bar 16 to rise, cams 8 being set to eifect this in a little less than half a revolution. The lifting-bar, being under projection 57 of the catch-bar moved forward by a key, raises it, lifting the corresponding assembling-bar 48. Projections 53 on the assembling-bar being so disposed as to engage with the particular parallel bars 38 necessary press up and move those bars directly over the projections, leaving all others at rest. This moves the corresponding links 37 45, which raise rods 36 46. Rods 36 move blocks 35 upward in the Sliding head 12 behind punches 27. Rods 46 work through the block 100 against ends 113 of blocks 110, causingthe 'blocks 110 to turn on rod 103. These blocks,

having ends 113 under ends 115 of blocks 116, cause blocks 116 to move on rod 117, raising end 115 and depressing end 121. The blocks 116, having pins 120, lift as one block all the blocks from the first block (at the left inFig. 13) to the last block moved, so that any block lying between blocks moved. and not moved directly by rods 46 will have its end 121 depressed. The arm 123, with pawl 122 attached to lever 125, acting under the retractile force of the spring 131, moves over the depressed ends 121 until pawl 122 engages with the first end 121 not depressed. Movement of arm 123 is retarded by the shape of cam 9, acting on end 125 of lever 125, and carries rod 135 with rack 137, which, being now unlocked, frees itself from pinion 138 and the rod 134 toward the punch-head. Rod 134 is connected with block 33, sliding in the socket 21, and pushes theblookbehind feed-holepunches28. Shaft 3, which has been continuously rotated by wheel 5, since the clutch was engaged by movement of a key, causes cam 7, by its projection 7 acting on roller 10 onshaft 11, to move head 12 and the punches 27 28, behind which blocks 35 33 have been placed, as above described, to perforate the ribbon previously placed in the slot 30. Continued revolution of cam 7 permits spring 19 to pull back head 12 with drawback-plate 20, which withdraws the operated punches. Cam 151, releasing end 150 of lever 146, permits spring 149 to 'for the formation of the desired character lOlS.

draw back end 145, which, acting on the arm 142, forces the rack 137 into mesh with pinion 138, locking the rack thereto. Cam 9 in the second half of its revolution engages with lever 125, moving it, with arm 123, rods 134 135, and block 33, to their original positions. Red 135, moving rack 137, locked to pinion 13S, moves the pinion, feed-wheel, and ribbon thereon forward a distance corresponding to the length of the character being punched plus the space between the charac- Piece 152 holds the ribbon against the feed-wheel. Pins 140 draw the strip forward into position to have another character punched therein by the next operation of either character-key. Shaft 3, having nearly completed one revolution, brings clutch-bolt into engagement with the wedge-shaped projection 88 of the bifurcated trip and as rotation continues, with piece 86 of said trip forcing piece 86 forward, bolt 90 is entirely withdrawn thereby from the hole 93 in driving-wheel 5, in which it is at the time extending. This projects end )4 beyond clutch 4, allowing it to come into engagement with spring 95, which counteracts the inertia of the shaft and returns said shaft to its original position. Spring 89, compressed by forward movement of piece 86, forces piece 86 backward with the shaft and bolt when returned by spring 05, preventing the end of the bolt from striking the balance wheel, thus, as shown at 00, Fig. 14, obviating wear and noise. Projection 58 on the operated catchbar 54 slips off rock-shaft frame 64, oscillated thereby, when said bar is raised by bar 16. This allows the rock-shaft frame to pass under projection 58 and to return to its original position to permit trip-piece 86 to be in readiness to withdraw bolt 90 to insure a positive stop after each single revolution of shaft 3, so that if the operator forgets to remove his finger from the depressed key or is too slow in removing it the machine will make but one revolution and will form but one combination of perforations, representing a singlecomplete character, for each movement of a finger-key. Cams 8 in the second half of their revolution lower lifting-bar 16 and cushioned bar 16, Fig. 2, attached thereto, returning bars 38 48, links 37 45, rods 36 46, blocks 35, 110, and 116 to their original positions, the bar 16, with cushion 16", insuring a positive return of the bars 38 and attachments thereto. Cam-151, operating on end 150 of lever 146 at the beginning of the revolution of shaft 3, brings the teeth 148 in mesh with the pinion 138, moving it slightly backward or forward and looking it, thus bringing the feed-wheel and the paper strip thereon to a fixed position, insuring exact regularity of the feedholes. The same movement of cam 151 moves end 145 into indent 143', unlocking arm 142 and freeing rack 137 from pinion 138. The tension device 160, made yielding by arm 188 and spring 190, keeps the strip taut, taking up all slack occasioned by elasticity, racing,

or adjustment of feed-wheel when teeth 148 engage with and lock pinion 138. Cover 184 is pivoted and furnished with a handle, and pin 183 has a knob for convenience in inserting a new ribbon or strip. Arm 159, operated by the strip, is carried toward the tension device when that portion of the strip between the tension device and the reel becomes taut. This operating through the spiral spring 174 causes the pawl 167 to engage with the ratchet-wheel 166 on the loose piece 163. The pawl 167, jointed to the lever 168, having the link 171 resting against the sliding head 12, is moved forward as the sliding head 12 moves forward, thus moving ratchet-wheel 166 and the paper-roll thereon, relieving the feed-holes from the strain of overcoming the inertia of the paper-roll. Lever 168 is returned by spring 170.

The finger-plate 108 at the center of the lower row of keys, Fig. 1, is shown of greater width than the others, and is a spacer to make spaces between words of a message, and is connected with two finger-key levers, one of which is connected by red 71 to a catch-bar and is used to operate the trip-piece 86. The bar48, to which this catch-bar is joined, has no projections 53 and will not, therefore, render any character-punch operative. The arm 123, moved forward a distance equal to one space beyond the ends 121 by the cam t), is moved back one space, being stopped by the ends 121, allowing lever 125 and parts operated thereby to advance block behind one feedhole punch and also to advance the ribbon one space. The other finger-key lever 74, attached to the spacing-finger plate 108, is connected by the rod 71 to the lever 106 and on the depression of the spacekey moves the blocks under the ends of the spacingbloeks 116 far enough to carry the several blocks 110 partially under the next blocks to the right, but not far enough to carry blocks 110 from the paths of movement of their individual operating-rods 46, (see Fig. 27, where bars 110 are shownin full lines directly under individual bars 116 and at 110 dotted in the position occupied when moved to the right, the same being shown on a smaller scale in Fig. 11,) so that whenever rods 46 are raised one more space-block will be lifted than would have been lifted for the particular combination being punched, giving one more feedhole than if blocks 110 had not been shifted. This permits the use of the space-key in conjunction with a character-key and consequently the perforating of a character with its space and an extra space at the same time. The first bar 116 at the left'is double the thickness of the other bars. This is because 110 character to be punched requires two spaces only. The shortest character, c, with its spaces, requires three feed-holes, and these three holes are provided for by means of said thick bar, which is the only bar that would be raised in punching c. If a single space is desired, as no character-punches are IIO then used, no space-blocks will be moved and but a'single feed-hole punch will be operated.

Rod 135i may be omitted, if desired, and block 33 left permanently behind feed-hole punches. The effect would be that all the feed-hole punches would move forward with each forward movement of head 12. In forming characters requiring the whole number of feed-holes all the feed-hole punches would punch holes; but in forming characters requiring a less number of feed-holes as many of the forward punches in the series as necessary would punch the paper, but the following punches would simply pass through holes punched at the preceding operation without resistance Having described my invention, I claim-- 1.
